Brown dwarfs in star forming clusters (NIRCam imaging + NIRSpec MOS – same cycle) Catarina Alves de Oliveira (ESA) Brown dwarfs represent by number a sizeable fraction of the stellar content of the Galaxy and their masses populate the transition between the stellar and planetary mass regime. There is not an accepted explanation for how they form, making them a key element in understanding the origin of stellar masses and their distribution. The new observational frontier is therefore the discovery and spectral characterization of the least massive brown dwarfs to test formation theories. This is the main driver behind this example NIRSpec/JWST proposal. We propose to obtain NIRCam imaging data to search for new candidate brown dwarfs down to the mass of Jupiter in the IC 348 cluster, followed by low and medium resolution spectra of those with NIRSpec MOS to confirm the nature of the candidates therefore improving constraints on the minimum mass of the initial mass function, and to search for spectroscopic signatures of their formation mechanism.
